Weather (8)
I believe the answer is:
elements
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">weather</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that elements is a type of weather)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for elements that I've seen before include "Constituents, ingredients" , "fire and water, say" , "Essential parts or the weather" , "Nitrogen and oxygen, e.g." , "Components or weather conditions" .)
